Application flied December 17, 1915. Serial No. 6i,423.

To-aZZ whom it may concern: I

Be it known that I, GLENN J. Baaas'rr, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Automatic Coin-Paying and Change-Making Machines, of which the following is a specification.

This invention relates to improvements in automatic coin paying or change making machines. 1 t

The objects of this invention are First, to provide a machine designed to automatically make change based upon the tendering of one dollar, and particularly to make change by the depression of one key when" the said change is a multiple of'five and the depressed key representsthe purchase price.

Second, to provide a machine having the key board in proximity-to the point of delivery. I

Third, to provide a machine having a key board easily covered by the hand, thus en abling the operator to follow out a touch system.

Fourth, to provide a machine ha ing a condensed ke board, thus enabling the but; tons to be spaced farther apart thereby rducing to a minimum the liability of do ressing more than one button.

Fifth, to provide a machine having a system of coin tube trays adapted to be indi vidually removed or removed in a block.

Sixth, to provide a mechanism for locking said tubes into position and a means for onlocking them, operated from the keyboard of the machine.

Seventh, to provide a machine havingcoin tube trays exposing every coin to the 111,1 view of the operator..

.Eighth, to provide in a machine a coin ejector mechanism which will absolutely catch and eject the precise number ofcoins re uired for'the given changei inth, to provide a machine wherein 'the ejectors when returned to their normal position will automatically and positively retor in position themselves behind the next coin or coins tobe ejected.

Tenth, to provide an e] ector'structure admitting of .a single spring to hold the ejecits normal position and to draw the same back to its normal position.

Eleventh, to provide a machine having a rock shaft mechanism with direct connections between said rock shafts and each cjec tor mechanism corresponding with the respective coin tubes.

Twelfth, to provide a machine having a practical and direct selecting mechanism f r operating any desired rock shaft from each of the respective key levers.

Thirteenth, to provide a machine having certain eliminating mechanisms whereby change may be made direct from fifty cents or twenty-five cents or both.

I Fourteenth, to provide a machine having a trap door structure whereby a slight movement of the same causes the coins to be re leased into the hand or a tray or delivery' I accomplish the objects of my invention I by the devices and means descrlbed in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a. part of this specification. in which:

Fig. XXVIII is a perspective view of the trap door hook 118. n the drawing similar reference characters refer to similar parts throughout the several views,"- and the sectionalviews are taken looking in the direction of the little arrows at the ends of the section lines.-

Referring to the drawings, I consider the reference characters as representing the parts themselves. The casing of my machine consists of the-side plates 1; the front plate 2, the combination rearand top plate 3 and the bottom plate 3. The front and rear plates are fastened to the lugs 2, secured to the side plates. The top .of'the machine is partially cut away so as to hold the coin tubes consisting of thetwo 10 tubes 4 and 5, the 1 tubes 6, 7, and S, the 5 tube 9, the 25.tube 10, and the 50 tube 11. The keyboard, as is usual in this type of machine,

,consists of rows of keys suitably stepped one A above the other asshown.

The whole machine is supported on the rubber feet 12. Theside platespartially constitute-the frame ofth'e-machine and are connected by .the square cross rods 13'and various round rods hereinafter described. are the two end plates-14 the-rock shafts,

turned up so as to carry the button 16 as shown. The other end of the key-levers ful crum about the key lever rod 17, said rod being secured to, the two end plates 14;

From each key lever is a vertically extending the hand operated trap door 7 key levers a re arm 18 adapted to connect to the draw bar bell .cranks- 19,'said bell cranks havingthe hooked portion20 for engaging the cross pin draw bar bell cranks are journaled by suitable bushings on rod 22, said rod being supported by a pair of auxiliary end plates :23. The rear end of. the draw bar bell cranks are pivotally connqcfed to the front end of the draw bars Bl. The rear end of the draw bars J l -jare pivotally connected to the draw bar levers 25. said levers are journaled by suitable bushings on the draw bar lever rod 26. Rod 26 is retained by the end plates 14. The draw bars and key levers are held in their normal position by springs 27 which are hooked to rod 28 supportedby depending arms 14' of end plates H. From the top' edge of draw bars 24 reject the ears 29, some projecting to the rightand some to the left, as shown in Figs. I1 andIX. Each draw bar has the necessary number of ears for forming the given combination as hereinafter described.

The various ears of the draw bars are gidapted to operate the short rocker arms 30 and the long rocker arms 31. Rocker arms 30 and 31 are rigidly connected to the rock 15 shafts 82 said rock shafts being journahul in the end plates 14:. Near the top and at the rear oi the machine and carried by the side -platcs is the ejector bell crank supporting rod 33. The rod 33 is supported at its con-- 35 for from cross rods 33' by strap 34'. Journaled ith suitable bushings on rod are the ejector bell cranks 34. One arm of each ejector bell crank 34 is connected to a corresponding long rock arm 31 by connecting link'35. The other arm of the bell crank is connectdto the corresponding ejector 3c and operates the same, the number of eject.- ors and ejector bell cranks being the same as the number of coin tubetrays- A rock Shaft is provided for and connected by a single mechanism to each ejector.

I have thus far shown in general the con- .ncction of the key levers to the ejeetors. The following portion of the description will show how I work the. combination necessary to get 90 in change, on the depression of the 10 koy as shown in Fig. VIII.

,The change e'epited by the machine will consist of ;li|')l e, a 25 piece, 2). 10 piece and a 595 piece, the various cjcctors kicking out tie said coins simultaneously. The

Luunber of cars on the lOl draw bar is four. These ears engage three of the short rockerarms and one long rocker arm. The short rocker arm 37 is connected to the 10 Mick shaft 38, that is, rock shaft 38 connected as previously shown to the ejector for kicking out a 10 iece. The long rocker.

arm 39 is directly operated by the 10" bar 80 and connects to the 5 ejector, as is shown in full lines in- Fig. VIII. Short rocker arm -t0 is connected to'rocker shaft 'lwhich in turn operates the 25 ejector. The short rocker arm 42 is connected to rock shaft 43 to which operates the50 ejector. Therefore after described.

when the 10 keyis depressed the 10 draw bar iSlDllllQd torwa rd and the ears of said bar engaging the "arious i-(u:ke arms turn the same about the respective rock shafts and as the various rock shafts carry a single long rocker arm the various ejcctors are operated to eject. the given coin.

I have constmlctml my machine so that th various draw bars when actuated, move fornard nearly in a straight line. \Vhrn one of the key levers is depressed the same has a slight forward displacement which is taken care oi. by the slot at the end thereof, rod 17 being grooved to retain the said levt-rs and permit such movement (Fig. VIII). It is evident. therefore, that the various draw bars can have on them the various cars necessary for operating dill crent short rocker arms or to operate one of the various long; rocker arms so that the re- 35 quired ejeeto may be operated to kick out the given change on the depression of the appropriate key.

With this selective. mcchanisn'i, my inathine is capable of a great many coinbiiiw tions. The various ears project from one side or the other for construction purposes only. Ti 2 arrangement of the various short and loin-,1 rocker arms on their rock shafts is clearly shown in planin Fig.1Il The long rocker arms are of various lengths so as to give the ejectors the proper travel necessary for ejecting the various size coins. The dinieaeiector has less movement than the half dollar ejector-s.

The following portion of my description will take up the-coin tube construction and the details of the ejector and the manner in which it kicks out a coin. Each coin tube (Fig. XVIII) consists of two pieces of sheet metal, the sides and back 44. being: 'lm'ined integrally and the bottom plate 4!) turns up db-45' see Fig. XX, and is riveted at 45 to the back of the tube. From the hack portion of the bottom plate and at the top thereof projects'the notched tongue 46. Near the .lower end of said back port-ion. projects a couple of notched ears 47; The notched tongue 46 and the notched cars 4;? are adapted to engage the slots 48 and 49115 respectively of the coin tube back'plate (it). lhe'coin tubes are held securely to the back plate by the screws 51 which screw into the boss 52 securely fastened to the said tube. The tubes are further held in place on the back plate by crossbar 53,. said her being pivotally mounted at one end and at the other end a notch engages the 'screw 55. This bar bears against the top of the notched ears 47 as shown in Fig. XVIII and is normally held in' place hyan outward spring tendency of the same against screw 54. The back plate is fastened to the back end of the machine by means herci in- .the bottom and at their lower ends form the coin retainers 55 .beneat which the bottom coins are ejected. These cars do not extend top edge thereof, said top edge bein while the coin is beingejected, so that the to the bottom. of the tube but are. just the proper height above the same so as to permit the necessary coin or coins to be ejected. At the dutside edge of bottom plate 45 and at the forward end thereof are the two guide ears 56, said ears serving to guide the coin when ejected from the tube. The bottom 45 is slotted at 57 to permit the ejector to slide therein and; is partially cut away at the front portion thereof so that the coin will not have to be pushed farther than necessary before it drops onto the discharge chute. Slot 57 also extends upwardly on the back wall of the tube as shown in Fig; XX.

The back wall of the coin tubes 44 at theirlower edge are also notched out at 58 as shown in Fig. XX. At the front end of ejector 36 and on each side thereof is an ejector catch 59 and an ejector clip 60 both made of hardened steel and securely riveted together. The ejector clip is separated from the ejector by a pair of washers 61.

On the top side and at the rear end of the ejector catch is a tooth 62 shouldered to the slightly rounded as shown in Fig. XXII. T eheight of the shoulder is a trifle less than the thickness of the coin to be ejected. The catch as thusv described will normally engage the edge of the coin and eject the same when a key is depressed. However, when the ejector position, the tooth is returnlng to its normal of the catch will yieldingly bear against the bottom coin, Fig. XXIII, until the tooth disengages the back edge of the coin and the ejector is again in its normal position, as shown in Fig. XXII. However, toinsure the tooth 62 to properly engage the coin,

the clip 60 is rounded on top and S0 proportioned that when the ejector is in its normal position, the catch will be properly set so as to engagexthe coin to be ejected by said clip bearing a ainst the bottom plate as shown in Fig. VIII. As the engaging end .59 of the catch advances the rounded'incline of the bottom of the notch engages the rear bottom edge of the coin thereby forcing the arm.which' carries the catch down slightly guide'clip 60 does not-actually bear upon the bottom of the coin tray and thus unnecessary wear is avoided: the main object of this clip 60 being to prevent the tension of the ejector arm from uplifting the coins during the return movement of the ejector, and when there are-but few coins left in the tray. This clip 60 is carried to one side of the catch 59 so that by simply twisting the e ector arm a bent outwardly the pm proper cooperative relation with of the coin tray.

The ejector catch that operates co 1n tube 8 isso designed as to catch two' pennies, thls being the only case in this machine where two coins are kicked out by the same ejector.

The notch 58 in the rear wall of tube 44: serves to allow the next to the last coin to drop into the same, as shown in Fig. XXIV, the top side of the slot engaging the top side of the coin. The coin is thus kept from jumping around in the tube from the up- Ward recoil of the ejector when the same is returning to its normal position, a thing which occurs in many machines when the tubes are nearly emptied and particularly when the machine is rapidly operated. In this connection, the clip 60 serves to limit the said recoil and prevents disturbing the coin and permits the engagement of the rear edge of the coin to be eifective.

Besides spring 27 for returning the released key lever to its normal position, a spring 62connccted to each ejector'serves to hold it yieldingly against the tiibes and return the same to their normal position. To insure the catch 59 to properly contact with the coin when in the normal position a projecting arm 64 strikes a stop strip 65 securely fastened to one of the frame cross rods 66. This, kick the ejector arms upward and is of great advantage when the machine is rapidly operated.

All of the ejectors are normally guided by the slots in the comb 67, Fig. II. The cross piece 68 serves to limitthe depression of the key levers. The floating structure of the ejectors, therefore, permits them to automati- 'cally position themselves and has reduced the sliding contact of the parts to a minimum. Each of the ejector bell cranks is mounted on a bushing 70 which turns on rod connecting link having an offset portion 71,

a pin 72 spring 73 of the pin.

riveted at the endthereof and a adapted to engage the stud 72 Therefore, when the spring is may be journaled in the ejector bell crank therefore, has a tendency to the bottom 34 as shown or the rocker arms and the spring snapped back to engage the stud end of hold the ejector'cranks or rocker arms in place, thus allowing an easy means for assemblmg'this portion of the machine.

At the left hand of the keyboard are three keys, --a release key designated by R and 50 ...1d 25 eliminator keys. these three keys bemg the pin and securely remainder of the keyboard. The purpose ofthe 50 and 25 eliminator'keys is to prepreferablyof a different color than the and ejecting the *"same. The release keys serve to release either the 50 of eliminator keys, or both, should it be necessary to do so when the same are unintentionally depressed, and also serve to release the mecha: nism which locks the coin tubes in place.

7 The key levers, draw bars, rocker arms and cars 70 and 71. These ears enga coins;

connecting links are similar to and operate as those reviousl described.

Figs. and x show the 25 eliminator key in the normal and de ressed position. On the draw bar for this ey are the two respectively the "short rocker arms 72m 73, said rocker arms being rigidly secured to the rock shafts 74 and 75 respectively. On rock shafts.- and 75 are the long roc er and 77 respectively. These connect by connecting links 78 and 79 respectively, to the eliminator levers 80 and 81 respectively, said levers being mounted on the rod 82 secured between the side plates 1. Projecting from one end of levers 80 and 81 is the pin 83. Therefore, when eliminator key 25-is de-. pressed the eliminator levers are tilted and pin" 83 bears against the ejector and depresses the same so the ejector catch W111 not "88 and the upper portion of the draw ar levers is the release rod 89, said relpase'rod being held between lates 90, F1g. XII, said plates being. ivotal y mounted on the draw bar lever sha t 26. When the 25 and 50 ejectors are held down b'yi -the depression of p the 25 eliminator key, the proper change will be made by the depression of the key rebresenting' a purchase under 25 9r between 50 and 75, as the 25 and 50 ejectors are not allowed to catch their respective The said ejectors, however, are ppshed forward as usual but when the key representing the purchase price isnormally in its depressed position the upper port on .91 of the "draw bar lever will contact with "the release rod 89. Release rod 89 is, therefore, rotated around shaft 26 and coacts with the pawl finger 88 thus lifting the pawl and releasing the elimlnator key draw bar from contact with finger 86, the eliminator levers springing back into place.

In the way of the 25 and 50 eliminator 'draw bar levers the release rod 89 is slotted, Fig: XI, so that the portion 91 will not interfere with the same when the keys are dearms 76' u said clips being secure pressed. When the 50 eliminator .key is depressed the 50 ejector is out of contact with its coin chute, therefore eliminating the ejection of any 50 piece for the proper change.

The action of the 50 eliminator rock shafts 74 and 75 are therocker arms 93 and 94, respectively. These connect by suitable springs tothe key lever shaft 17 and aid in bringing the said levers backto their normal position. i

The release key lever is connected similarly as the other levers ,(Fig. XV) except that the upper half 95 of'the drawvbar lever pivots slightly farther forward on the draw ar than do the respective levers on the other draw bars. The release key lever, therefore, needs only to be depressed a short distance when the release draw bar le\ er contacts with release rod 89, thus releasing the 25 and 50 eliminator keys should they be depressed.

Between the ends of the back plate are the two positioning slots 96, (Fig. 'XVII).

.These slots are ada ted to engage the studs 97, Fig. 11. The ower edge of the back plate is retained in the hookedportion 98 of a pairof positionin back plate clips 99, fastened to a couple of cross rods 100 retained by the side plates 1. Pivotally mounted on shaft 101, Fig. XV, suitably retained by the side plates 1 are a pair of locking rod side plates .102. The two lates are connected at their front ends by t clocking bar 103. The other end done of the plates connects b a connecting link 104, here shown out of ace,-to release t e release rock shaft 106. The rear end of' the other end rocker arm secured to plate 102 is-connected to one end of 5 ring 107, the other end of said spring ,ing

hooked to cross rod 69. When the release key is in its normal positionthe rocking bar 103 is, positioned just above the cars ,47 of end coin chutes 4 and 11. As the coin chutes are fastened to the back plate and the back plates held in the machine, gas previously described, the same cannot be lifted upward and out of contact with studs 97 as saldears' '47 will come against locking bar 103. The

beveled portion .of cars 47 serve to easily displace the locking bar when the back plate is nserted in the machine. When the release "key is depressed, the end plate 102 turning about rod 101 places bar 103 out of any possible contact with the cars 47, therefore enabling the back late and the tubes fastened thereto to be li ted out, spring 107 serving to bring the plate 102 back to normal position.

I have, therefore, provided an easy way of replacing and removing the coin. tubes en bloc, together with the back plate.

By reference back to the description of my coin trays, consistin of pieces 44 and 45 it will be understood that by removing the screws 51 and the crossbar 53,'which are shown in assembled positions and serve to lock all my trays u on a common carrier, that each tray their ecomes an independently removable tray and its ears are acted upon by the common locking shaft 103 as they project through the late 50. The engaging ears 47 ofeach tu e are in the same plane. When in normal positions, by depressing the-release key in the keyboard and while screw 51 and cross bar 53 are removed, any tray may be taken from the carrier plate 50 and conveniently replaced. This is an important feature as it enables an operator to have filled tubes of coin mostly used which can replace the empty ones instantly. This feature is stated as the fifth object on page 2. V

In the central part of the key-board of my machine are the 1, 2, 3 and 4 keys. Thwe operate independently of all the other mechanism, that 15, none of the other keys will operate the e ectors for tubes 6, 7 and 8. The'mechanism for these four ke s is the same as that for the other keysff he 1 key when depressed serves to eject lit out, of tube 7 the 2 key when depressed serves to eject 1 out of both tubes 6 and 7, the 3 key when depressed serves to eject 1 out of tube 6, and 2out of slot 8, and the 4 key when depressed serves to eject 1 out of tubes 6 and '7 and 2c out of the tube 8.

The release rod 89 is notched in we of the 1, 2, 3 and 4 draw bar levers so that t ese keys will not release the or 50 eliminator keys when depressed. Therefore, when change not a multiple of five is to be made "i the key representing the'first multiple of five above the purchase price and the key representing the difference between the archase price and the said-multiple a ove mentioned are depressed- -vizz should the amount of the purchase price he 27 and the amount paid 50, the 50 eliminator key would be depressed and the and 3 key (I ressed, iving 23 in diange. I

nside 0% the housing and'beneath the front end of the ejectors is the apron 108 supported by the lugs 109 secured in the side plates. Between the apron 108 and the front plate 2 is the slanting discharge chute 110 sloping downwardly from the ejector to the trap door 111, said chute restin on'the bars112, secured by the apron an the front plate. The trap door 111 is piv-v otally mounted on the pin 112 and is provided with a curved bottom piece 120 to centralize the coins as they are ready fordelivery, said pivot pin being fixed in block 114 secured to apron 108. door 111 is the finger piece 115. Therefore, when the coins are ejected from the coin tubes they slide down the chute 110 onto trapdoor 111. Thus by pushing ngainst closed position.

I for such use as in making up .a pa

for the use of a paying teller in a ank. I

Beneath trap the trap door is tilted downwardly and the money may slide into the palm of the hand, side piece 116'serving to prevent the money from sliding sidewise over the door. Spring 117 serves to brin the door back into its owever, should it be desired to hold the door open the hook 118, shown'in Fig. XXVIII, which is pivotally mounted to a small auxiliar front plate 119, can ,be swung into position and holds the trap door downward as shown in Fig. XXVII. The front and side walls in the vay of said tray are cut away as shown in Fig. I.

The machine that I have shownhere is the one in which I have embodied my invention for the market but there are many modifications of the same. For instance, by rearranging the key buttons Ican make the same machine serve as a machine pa ing any desired amount of change under 1.00 roll or can place both characters in difierent colors upon each key which is a multiple of five,

making the machine into an automatic change maker and payer, or virtually having two machines in one.

If I were to make the machine a payer, I would have the buttons indicate the amount of change ejected, that is, the 30-button would eject 30 cents. If I were to makethe-machine both a,payer and an automatic change maker, I would have on the button shown, as for instance, the

button, 95in, one color anda 5 in another color and so on with the others which are multiples of 5. The penny buttons, however, would not be changed. With the condensed keyboard as shown, I am enabled to spread the buttons farther apartthereby reducing the liability ,of unintentional de pression of more than one button to a minimum. It will be noted that all of the parts of importance operate on the pivdtal principle and nopart slidesin proximity to any other thereby causing friction and endan ering accuracy. By arranging the penny uttons in the center of the main'key 'board, it enables the operator to strike them simultaneouslywith the other, the advantage of which is plain. y

I have shown my chin paying or change makin machine embddied in a specific de-' sign. Vhile it has a large number of parts they are -in a large measure duplicate stampings, making the machine very economical to manufacture. I desire to state, however, that, broadly considered, these details can be greatly modified. Cast metal might be utilized in place of sheet metal in many change I arts and other modifications will readily well as broadly, as pointed out in the ap-' pended claims.

Having thus described my invention, what claim as new and desire to secure by Letters Patent, is: m; j
